CURVILINEAR FABRIC.

Application filed April 23, 1926.

This invention relates to a curvilinear fabric capable of general utility but partic ularly designed for use in the construction of lining strips for automobile tires.

It is the general object of my invention to provide a curvilinear fabric for such purposes which is of a strong and durable construction. and which can be produced at relatively low cost and with great rapidity.

A furtl'ier object of my invention is to provide a fabric of this type which can be woven by the use of the standard equipment of a narrow ware mill or factory and with only slight and inexpensive alterations therein.

It is a more specific object of my invention to provide a curvilinear fabric woven as a single integral structure, curved transversely as Well as longitudinally, and preferably of varying thickness from edge to edge.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly set forth in the appended claims.

A preferred form of the invention is shown in the drawings in which 1 is a perspective view of a portion of my in'iproved fabric; and

Fig. 2 is a sectional elevation, taken along the line 2 in Fig. 1.

Referring to the drawings, it will be seen that my improved fabric is curved longitudinally so that it naturally assumes a eircular form and that it is also curved transversely with the convex side inward and the concave side outward with respect to the longitudinal curve.

The fabric is preferably varied in thickness transversely, the center portion of the fabric being of substantial thickness and the edge portions of the fabric being relatively thin. In the preferred form, the fa ric is made as a multiply structure, with certain of the plies of less than the full Width of the fabric. A certain proportion of coarser material may be worked into the middle portion of the fabric, to increase the thickness desired.

In order to prevent undue shrinkage of the. thinner edges of the fabric, I prefer to form the edge portions of a finer material or of a closer weave than the center portion, this difference in weave compensating for the difference in thickness and causing a Jig.

Serial No. 104,180.

substantially uniform shrinkage of the entire fabric.

The fabric as above described is woven as a single integral structure, preferably in a narrow ware loom, the difference in thickness being attained by a proper selection and distribution of the warp threads in the reed spaces, and the transverse curve of the woven material being accommodated by take-up rolls and winding rolls of corresponding cross section.

A fabric constructed as above described has been found to be extremely strong and durable and to be particularly well adapted for use as an inner lining strip for automobile tires, where the thicker portion of the strip covers the space between the two side walls of the outer tire, while the thin edge portions are clamped between the inner tube V and the outer tire.

The fabric may be woven in a continuous piece and may be thereafter cut up in any desired lengths. The cost of manufacture is thus very much less than that of certain built-up constructions heretofore used for similar purposes.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims, but what I claim is 1. A curvilinear fabric woven as a single integral structure and adapted to be used as a tire lining strip, said fabric being curved longitudinally and being also curved in cross section and being concave transversely on its outer face and convex on its inner face and said fabric having two full selvage edges.

2. A curvilinear fabric woven as a single integral structure and adapted to be used as a tire lining strip, said fabric being curved longitudinally and being also curved in cross section and having its outer face convex longitudinally and concave transversely and having selvage edge portions reduced in thickness.

3. A curvilinear fabric woven as a multiply structure curved in cross section both longitudinally and transversely, having a transversely concave outer face and having selvage edge portions of reduced thickness.

In testimony whereof I have hereunto affixed my signature.

JOHN V. MOORE.
